Abstract: The invention according to one aspect provides oxygen sorbent materials, which are able to remove trace amounts of oxygen in either a gas-flow or an enclosed system over a wide temperature range. In particular, the invention relates to bulk solid oxygen sorbents that can lower equilibrium oxygen concentrations to below 1 part per trillion (1 ppt). The oxygen sorbents have high surface area, nano-sized crystalline mixed oxides that include cerium oxide, zirconium oxide and preferably yttrium oxide, and an aliquot of catalytic materials such as precious metal. The present sorbents can work in noxious environments, since the materials are not sensitive to toxic elements, which would typically poison conventional catalysts. In another aspect, a product and method for fabricating an opto-electronic device that includes a getter material, incorporating an iteration of the sorbent material, is provided. The getter material operates by bulk transport and has a capacity to absorb and retain large quantities of oxygen per volume and other contaminants over a wide temperature range. This is a useful feature for opto-electronicnullalso known as photonicnulldevices, especially those with polymeric components, since they often suffer from photo-degradation caused by the presence of gaseous oxygen and other contaminants in the optical pathway.

Abstract: The invention relates to shaped bodies containing organic-inorganic hybrid material in addition to gold and/or silver particles, to a method for the production thereof and to the use of the same as catalysts. The shaped-body catalysts are characterized by a longer service life than the original powder catalysts, in addition to a high selectivity and productivity. The inventive shaped-body catalysts also enable pressure losses to be kept to a negligible level in technically sophisticated reactors, for example fixed-bed reactors.

Abstract: Solid materials have been developed to remove contaminating metals and organic compounds from aqueous media. The contaminants are removed by passing the aqueous phase through the solid materials which can be in molded, granular, or powder form. The solid materials adsorb the metals and the organics leaving a purified aqueous stream. The materials are sol-gel and or sol-gel and granulated activated carbon (GAC) mixtures. The species-specific adsorption occurs through specific chemical modifications of the solids tailored towards the contaminant(s). The contaminated solid materials can then be disposed of or the contaminant can be removed and the solids recycled.
